Title: Improvements relating to the production of reforming catalysts
IPC: B01J21/04
Filed: 1961-01-19
Abstract: A solution of an aluminium alcoholate in a hydrocarbon solvent is hydrolysed with an excess of water or aqueous ammonia at 0 DEG -50 DEG C., the solvent and alcohol are removed without ageing the resulting hydrated alumina, the latter is then composited with a platinum group metal compound while in hydrogel form and then dried and calcined to produce a reforming catalyst, the temperature subsequent to hydrolysis and prior to drying being maintained at from 0 DEG -35 DEG C.  Preferably the aluminium alcoholate is aluminium isopropoxide.  To effect hydrolysis water or aqueous ammonia may be added to the alcoholate solution.  Alternatively hydrolysis may be effected by using water and the hydrated alumina may subsequently be treated with aqueous ammonia.  The only specified platinum group metal compound is chloroplatinic acid which may be reduced to sulphide by passage of H2S through an aqueous solution thereof. Comparative examples are given in which catalysts according to the invention are used to reform gasolines for example under the following conditions: Temperature 750 DEG -1050 DEG F.; Pressure 0-1000 p.s.i.g.; Space velocity 0,01-10 v/v/hr.  Gas Rate S.C.F. of H2/B 0-15,000.  Results are compared with those obtained using conventional catalysts.

Title: Improvements in ventilating and air supply systems
IPC: B63J2/02
Filed: 1930-01-22
Abstract: 341,275. Ventilating and heating ships' cabins &c. NEILSON, T. and MARSHALL, J., 11, Cogan Street, Pollokshaws, Glasgow. Jan. 22, 1930, No. 2194. [Class 137.] In ventilating apparatus in which air is supplied by means of a fan or the like to a main supply trunk for distribution to a number of rooms or other enclosures through outlet devices comprising directional or rotary nozzles, and which is intended more particularly for the ventilation and temperature regulation of passenger accommodation aboard ship, heating means are associated with said air outlet devices for heating the air prior to its exit therefrom. Air is supplied from a fan through a main air trunk 5 and a series of ducts 6 to the enclosures to be ventilated, the outlet to each of the enclosures being through a directional nozzle 8 such as is described in Specification 282,323, [Class 137, Ventilation]. Before reaching the nozzle, the air, which may have been previously heated or conditioned, traverses a heating unit A comprising a cup-shaped quartz glass deflector 10 and an inner hollow cup-shaped shell 11 of refractory material, the latter carrying an electric heating element 13 with a number of tappings enabling the degree of heating to be controlled by means of a conveniently disposed regulator 17. Passage of air through the duct 6 and heating device is controlled by a valve 7 operated by a Bowden wire 15 from a control handle 18. To prevent the current being turned on while the valve 7 is closed, the handle 18 is adapted, by means of a contact segment 19 and contacts 20, 21, to break the circuit when the valve is closed. As an additional safeguard against overheating a relay 22 is adapted to make the circuit to the heater only when the motor control panel 24 has been manipulated so as to switch on the motor driving the fan. A heating medium other than electricity may be used, such for instance steam flowing in pipe coils. The directional nozzle 8 may be replaced by a rotary nozzle such as is described in Specification 332,024, [Class 137, Ventilation].

Filed: 1927-01-27
Abstract: 277,219. Gilliver, G., and Pascall, F. Jan. 27, 1927. Thermal switches; actuating; contacts. -The bimetal plate 3 of brass and the steel known under the registered Trade Mark " Invar " is fixed to a plate 2 and connected by a helical spring 9 with a contact arm 7 working between contacts or stops 12, 13. The contact arm 7 is pivoted in a groove in a bracket 4 which is also apertured to allow the passage therethrough of the spring 9, a slit 8 being provided in the arm 7 for the same reason. The plate 3, which is cut away at 15 so that it will cool much more rapidly, has a resistance coil 14 wound round it or arranged adjacent to it, for instance in the space 5. Normally, the spring 9 holds the arm 7 against the stop 12, but when the plate 3 heats up it moves so that the line of action of the spring crosses to the other side of the pivot of the arm 7, and the spring rapidly moves the arm against contact 13. The resistance 14 is now short-circuited and the strip cools and brings about a similar action in the reverse direction. One or more contacts can be arranged on either side of the arm for a two or more way flasher, and the periodicity can be regulated by screws 12<a>, 13a. A cover may be provided.

IPC: F42B12/44
Filed: 1918-02-12
Abstract: 130,391. Vautin, C., and Thermalloy, Ltd. Feb. 12, 1918. Drawings to Specification. Thermo-aluminic mixtures.-The Specification describes various thermo-aluminic mixtures suitable for making incendiary projectiles, the compositions containing, as an ignitable binding- material, sulphur with or without the addition of a metallic sulphide. In one instance, a mixture of finely-divided aluminium and sulphur is incorporated with an ordinary thermo-aluminic mixture or with "thermalloy" (a mixture containing aluminium, zinc, and ferroso-ferric oxide). The ingredients are intimately mixed, and then may be heated until plastic, the material thus obtained being cast into the desired form, or the mixture may be moulded under pressure without heating. Alternatively, a metallic sulphide such as iron pyrites is finely ground and mixed with sulphur; the mixture is heated and stirred until fluid and is then cast and allowed to set hard. This hard product is ground and added to a thermo-aluminic mixture, and the mass is treated as in the previous case. Reference has been directed by the Comptroller to Specification 130,360, [Class 9 (i), Ammunition &c.].

Title: Improvements in or relating to Sewing Machines.
IPC: D05B15/06
Filed: 1916-02-22
Abstract: 100,112. British United Shoe Machinery Co., (Assignees of Eppler, A.). Feb. 23, 1915, [Convention date]. Addition to 730/15. Boot - sole sewing - machines, welting and turnshoe.-In welting-machines as described in the parent Specification, means are provided for feeding a length of welt greater than that required for each stitch and retracting the excess of welt, for measuring the amount of welt which may be pulled off when the shoe is removed from the machine, and for operating cutting and welt-end-holding means. The invention is described as applied to the machine described in Specification 19679/11, and comprises a welt guide 26 normally held stationary and provided with a spindle 54 mounted in the frame of the machine. The other member of the feeding-device consists of a roll 30, with peripheral teeth 32, mounted on a stud 34 secured to a lever 36, pivoted to the feed-arm 40 and held adjustably against the welt by a spring 42. The arm 40 carries the shaft 50, to which is clamped an arm 56 with a rack, which is engaged by the rack 68 on one arm 60 of a bell-crank lever, the other arm of which has a sliding connexion 70 with the stud 72, upon which is mounted the cam-roll 74 of the lever for operating the slide carrying the channel guide 16 and awl 14. The cam-roll is reciprocated by the feed-cam 76 and rocks the arm 40 and, through the spring-pressed pawl 48 and ratchet 46, roll 30. The forward stroke of the arm 40 is adjusted so as to provide a greater amount of welt than is required by the length of stitch, and the slack is withdrawn during the backward movement of the arm till the pull on the welt between the roll 30 and the stitching point overcomes the resistance of the spring pawl 48. The welt guide 26 also acts as a measuring-device when the shoe is removed from the machine, and, for this purpose, the spindle 54 has secured to it an arm with a slot of adjustable length engaged by a fixed pin on the frame. This arm is connected by a link 90 with an arm 88 on a rock-shaft 86, which is held stationary during the sewing operation, by the latch 78 and rod 80 passing through a slot 82 in an arm 84 on the shaft 86. When the machine is stopped, the latch is oscillated and forces the rod 80 upwards, releasing the rock-shaft 86, and the pull on the welt by removal of the shoe rotates the guide 26 till the fixed pin engages the end of the slot in the measuring-arm. The connexions of the measuring-arm with the shaft 86 are adjusted so that forward pull on the welt oscillates a latch 100 on the rock-shaft, releasing a clutch by which the toothed arm 104 and bevel-wheel 106 are actuated to drive the severing-device 102. The rock-shaft with its connexions to the measuring- arm, and clutch-operating and locking mechanism are as described in Specification 19679/11.

Title: Colour television receiving system
IPC: H04N9/16
Filed: 1954-01-29
Abstract: 746,295. Colour television. STANDARD TELEPHONES & CABLES, Ltd. Jan. 29, 1954 [Feb. 2, 1953], No. 2748/54. Class 40 (3). Photo-cells 33, 34 and 35 operating in conjunction with red, green and blue filters 36, 37 and 38 view the screen 22 of receiver cathode-ray tube 21 comprised of a regular or random mosaic of red, green and blue phosphors (or monochrome phosphors and filters) to derive signals indicating the disposition of the various colours throughout the mosaic, the signals being stored as charge patterns in storage tubes 39, 40 and 41 scanned synchronously with the raster in tube 21 and utilized subsequently to control the release of the electron beams in tube 21 such that they impinge the screen only when the phosphors instantaneously scanned correspond in colour to the received signal. At the commencement of operation, the electron beams in tube 21 are set to a high level to produce uniform screen illumination independent of the received signals (or the receiver is disconnected) and the photo-cell signals are applied to recording electron guns 3 in the associated storage tubes. Thereafter the photo-cell outputs are disconnected by switch 45. The signals are regenerated by reading beams from electron guns 2, and the operation is such that the signals may be regenerated continuously without effacing the charge storage patterns. Incoming signals at receiver 46 are applied simultaneously to the three cathodes of guns 28, 29 and 30 and also control the normal scanning circuits and a colour sync. separator 54 via sync. separator 47. Colour control circuits 56, 57 and 58 are thereby actuated in dependence upon the colour being received and supply a first input to gate stages 42, 43 and 44. A second input is derived from the respective storage tubes 39-41 and the gates function to release the beam of the associated electron gun only when an input is received simultaneously from both sources. Reference is made to the use of received signals in both frame and dot sequences. A second colour sync. separator 55 may supply an output in common to the reading guns of all the storage tubes or may operate the tubes separately in synchronism with the received colours. In an alternative arrangement, colour control circuits 56-58 may be inserted in the paths between the storage tubes and gates. In yet another arrangement, Fig.2a (not shown), the signals from receiver 46 are applied to the cathode-ray tube guns through gate stages 42- 44. A single electron gun may replace the three guns 28-30 shown in Fig. 2. Specification 723,174 is referred to.

Title: Improvements in or relating to the production of porous concrete products
IPC: C04B28/22
Filed: 1948-01-30
Abstract: Porous concrete products, particularly cross-moved artificial stone blocks of porous concrete are produced by adding to slate ashes and lime or to slate ashes and a material containing lime in excess, sugar in sufficient amount that an acceleration of the reaction between the ashes and the lime-containing material is attained. Porosity may be produced by the addition of aluminium powder.  The best blocks are obtained by arranging that the direction in which the stone-forming mass moves during gas formation is in the horizontal direction with respect to the stone block positioned in the wall.  In an example 4 kgs. of a mixture of burnt lime and slate ashes so chosen that the elements present were in the proportion required for neutral monocalcium silicate were finely ground and then mixed with 2.10 to 2.70 grams of aluminium powder and 2.0 grams of sugar.  1.12 litres of water was added and the mix poured into a mould in which it set in 15 minutes.
